How Much Caffeine Is Safe?
The U.S. Food and Drug Administration (FDA) recommends adults consume no more than 400 milligrams of caffeine daily. That’s the equivalent of about four cups of coffee or eight cups of black tea. Caffeine supplements are usually 200 milligrams per pill. Many drinks do not list how much caffeine they have on their labels, but you can often find an estimated amount with a quick search on the internet.
There’s no one amount of caffeine that’s right for every person. People metabolize caffeine at different rates, which means one person can feel extremely affected by a small dose of caffeine while someone else might need three cups of coffee to feel the same jolt. However, the more caffeine you consume and the more frequently you consume it, the more likely you are to build up a tolerance.
Caffeine Is a Drug
It’s easy to forget that caffeine is actually a drug. Unlike opioids or alcohol, caffeine doesn’t lead to impaired driving or severe intoxication. Caffeine increases alertness and focus instead of dulling your reactions. But while it’s the most commonly use drug in the world, caffeine is still a central nervous system stimulant, just like amphetamines. That means it’s addictive, as everyone with a morning coffee or soda habit knows. The more you regularly consume caffeine, the more likely you’ll experience caffeine withdrawal.
